A Peerless pump
transporting quarry water used for service water (cooling) and
process water (slurry) in a cement plant fouled every 10 - 30 days
and required an acid wash each time. The pump was mounted on a
floating platform located in the quarry. The pump had a 8" intake
pipe and a 12" output pipe transporting the water one half mile.
The CaCO3 of the quarry water was 400 ppm. The pump
fouled every ten days in the winter months and every thirty days
during the summer months. A crane was required at each of these
shutdowns to remove and acid wash the pump. The cost for this
process was $1,000 per cleaning or $24,000 per year.

Solution:

The Electronic Descaling 2000 unit was installed on the pump intake.
Since the intake pipe was under water, a ceramic coated coil was used for
the protection from high pH water.

The pump now operates continuously at maximum efficiency (56 psi).

The elimination of the acid wash has significantly reduced
maintenance costs.
